I'm desparately looking for a way to disable snap-scrolling in Excel 2016 for Mac. Basically as you scroll Excel will continually try to keep the cell you're focused on in the centered. So when you're working on a large spreadsheet and try scrolling up/down, Excel will snap you back. To say it's infuriating is an understatement - I'm close to downgrading.
Looks like this was fixed.
I had the same problem until I upgraded by office from 2014 to 2017. Now I have office 2017 [version 15.33 (170409)] and I can scroll by pixels using Mouse as well as Laptop trackpad. I am using MacOS Sierra version 10 operating system.
